Intelligent warehouse elevator coupling device

Abstract

This utility model relates to the field of connecting device technology, specifically a connecting device for an intelligent warehouse elevator. It includes a horizontally positioned lifting platform body and two symmetrically arranged support beams, with a crossbeam fixedly connected to the top of each support beam. The advantages of this utility model are: a cylinder drives a telescopic frame to slide within a groove until the inner side of the telescopic frame is in contact with one side of the lifting platform body. Then, a first motor starts, driving a lead screw to rotate. Through threaded transmission, a drive plate slides within the telescopic frame, allowing an insert plate to pass through a slot and engage with the lifting platform body. At this point, the PLC control system controls a second motor to drive a bidirectional lead screw to rotate. Through threaded transmission, two moving plates simultaneously approach the insert plate until a locking pin is inserted into a locking hole, locking the end of the insert plate away from the drive plate and preventing slight slippage of the insert plate relative to the lifting platform body.

Description

Technical Field

[0001] This utility model relates to the field of connecting device technology, and in particular to a connecting device for an intelligent warehouse elevator. Background Technology

[0002] In modern smart warehouses, elevators, as a key piece of logistics equipment, play a crucial role in the vertical transportation of goods. To improve warehouse operational efficiency and loading / unloading speed, smart warehouse elevator coupling devices have emerged. The initial design purpose of this device is to optimize the connection between the elevator and the platform, ensuring stability and safety during loading and unloading. As the name suggests, the elevator coupling device is a mechanical device specifically designed to lock the stationary elevator platform. Its core component, the locking pin, can precisely insert into one side of the elevator platform, thus forming a stable connection. This design not only improves the stability of the elevator platform but also effectively prevents safety hazards caused by swaying during loading and unloading.

[0003] In practical applications, traditional lifting platform coupling devices have some obvious problems. Especially when loading and unloading heavy goods, the lifting platform often experiences a certain degree of shaking. This shaking can cause the locking pins to slip slightly relative to the lifting platform. Over time, this can easily lead to wear and tear on the coupling device components, thereby affecting its overall performance and safety. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to propose an intelligent warehouse elevator connection device to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides an intelligent warehouse elevator coupling device, comprising a horizontally arranged lifting platform body and two symmetrically arranged support beams. A crossbeam is fixedly connected to the top of each of the two support beams, with the crossbeams corresponding to the support beams front and back. A sliding groove is formed on the bottom surface of each crossbeam, and two symmetrically arranged recesses are formed on the inner wall of each groove. A cylinder is fixedly connected to the inner wall of each recess, and a transmission plate is fixedly connected to the output end of each cylinder. A telescopic frame is fixedly connected between the two transmission plates. The telescopic frame is slidably connected to the crossbeam via the sliding groove. A first motor is fixedly connected to the side of the telescopic frame away from the lifting platform body, and a lead screw is fixedly connected to the output end of the first motor. The lead screw is rotatably connected to the telescopic frame via bearings. A drive plate is threaded onto the outer surface of the lead screw, and the drive plate is slidably connected to the telescopic frame. Two symmetrically arranged insert plates are fixedly connected to one side of the drive plate. Both insert plates penetrate the telescopic frame and are engaged with the main body of the lifting platform. Two frames are fixedly installed at the bottom of the main body of the lifting platform via bolts. A second motor is fixedly connected to one side of each frame. A bidirectional lead screw is fixedly connected to the output end of each second motor. The bidirectional lead screw is rotatably connected to the frame via bearings. Two symmetrically arranged moving plates are threaded onto the outer surface of the bidirectional lead screw. Locking pins are fixedly connected to the side of each moving plate near the insert plate, and both locking pins are engaged with the insert plates.

[0007] Preferably, each of the above-mentioned solutions has locking holes on both the left and right sides, and both locking pins are engaged with the insert through the locking holes.

[0008] Preferably, in any of the above solutions, two symmetrically arranged slots are provided on the side of the lifting platform body near the crossbeam, and both insert plates pass through the telescopic frame and are engaged with the lifting platform body through the slots.

[0009] Preferably, in any of the above embodiments, a first guide rod is fixedly connected to the inner wall of the frame, and both of the movable plates are slidably connected to the first guide rod.

[0010] Preferably, in any of the above solutions, the inner wall of the slide is fixedly connected to two symmetrically arranged T-shaped connecting plates, and the top of the telescopic frame is provided with two symmetrically arranged T-shaped connecting slots, and the telescopic frame is slidably connected to the T-shaped connecting plates through the T-shaped connecting slots.

[0011] Preferably, in any of the above solutions, the inner wall of the telescopic frame is fixedly connected to two symmetrically arranged second guide rods, and the drive plate is slidably connected to the second guide rods.

[0012] Preferably, in any of the above solutions, two symmetrically arranged limiting posts are fixedly connected to the inner wall of each groove, and the transmission plate is slidably connected to the limiting posts.

[0013] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0014] Once the lifting platform body reaches the appropriate height, the PLC control system activates the cylinder to drive the transmission plate to slide inside the groove, which in turn drives the telescopic frame to slide inside the slide rail until the inner side of the telescopic frame is in contact with one side of the lifting platform body. Then, the first motor starts and drives the lead screw to rotate. Through threaded transmission, the drive plate slides inside the telescopic frame, causing the insert plate to pass through the slot and engage with the lifting platform body. At this time, the PLC control system controls the second motor to drive the bidirectional lead screw to rotate. Through threaded transmission, the two moving plates move closer to the insert plate simultaneously until the locking pin is inserted into the locking hole. This locks the end of the insert plate away from the drive plate, preventing slight slippage of the insert plate relative to the lifting platform body and reducing the wear rate of the insert plate during use.

[0024] As an optional technical solution of this utility model, each insert plate 11 has a locking hole 17 on both the left and right sides, and two locking pins 16 are engaged with the insert plate 11 through the locking hole 17. Through the engagement design of the locking hole 17 and the locking pin 16, a stable connection between the insert plate 11 and the lifting platform body 1 is achieved, which enhances the structural stability of the connecting device.

[0025] As an optional technical solution of this utility model, two symmetrically arranged slots 18 are opened through one side of the lifting platform body 1 near the crossbeam 3. Both insert plates 11 pass through the telescopic frame 8 and are engaged with the lifting platform body 1 through the slots 18.

[0030] A smart warehouse elevator docking device, the working principle of which is as follows:

[0031] 1): When the main body 1 of the lifting platform moves to a suitable height, the PLC control system will activate the cylinder 6 to drive the transmission plate 7 to slide inside the groove 5, which in turn can drive the telescopic frame 8 to slide inside the slide 4.

[0032] 2): After the inner side of the telescopic frame 8 is in contact with one side of the lifting platform body 1, the first motor 9 will start and drive the lead screw 91 to rotate. Through the threaded transmission, the drive plate 10 can slide inside the telescopic frame 8, and the insert plate 11 can pass through the slot 18 and engage with the lifting platform body 1.

[0033] 3): The PLC control system will control the second motor 13 to drive the bidirectional lead screw 14 to rotate. Through the threaded transmission, the two moving plates 15 can be driven to approach the insert plate 11 at the same time until the locking pin 16 is inserted into the locking hole 17, which can lock the end of the insert plate 11 away from the drive plate 10.

[0034] In summary, this intelligent warehouse elevator coupling device, after the main body 1 of the lifting platform moves to a suitable height, the PLC control system will activate the cylinder 6 to drive the transmission plate 7 to slide inside the groove 5, which in turn can drive the telescopic frame 8 to slide inside the slide groove 4 until the inner side of the telescopic frame 8 is in contact with one side of the main body 1 of the lifting platform. Then, the first motor 9 will start to drive the lead screw 91 to rotate. Through the threaded transmission, the drive plate 10 can be driven to slide inside the telescopic frame 8, which can drive the insert plate 11 to pass through the slot 18 and engage with the main body 1 of the lifting platform. At this time, the PLC control system will control the second motor 13 to drive the bidirectional lead screw 14 to rotate. Through the threaded transmission, the two moving plates 15 can be driven to approach the insert plate 11 at the same time until the locking pin 16 is inserted into the locking hole 17, which can lock the end of the insert plate 11 away from the drive plate 10, preventing the insert plate 11 from sliding slightly relative to the main body 1 of the lifting platform and reducing the wear rate of the insert plate 11 during use.
